PAUL CASEY last night revealed that Scots cyclist Graeme Obree is his inspiration as he strives to rebuild his game and get back to the Ryder Cup stage.

The 35-year-old is on the comeback trail after an injury-ravaged two years saw him plummet from a career high of third in the world to the low of losing his PGA Tour card.

But after a wretched summer saw him shooting scores in the 80s, Casey is seeing signs of improvement.

And he has vowed to prove wrong the doubters who think he’s yesterday’s man.

Casey, who narrowly missed the Dunhill Links cut, said: “I don’t have anything to prove to anyone else but I do have something to prove to myself.

“If I was out on the golf course and heard someone say, ‘There’s Paul Casey. He played in three Ryder Cups and won a bunch of tournaments’, then in my eyes – and excuse my language – that would be a lot of bulls*** because I still have so much more to accomplish in this game.

“I saw this TV piece on Graham Obree the other week and he’s out to try to break the human land speed record.

“He’s building this handmade bike pretty much in his kitchen and he’s trying to crack 100mph. He has gone through his problems but said, ‘I’m not scared of crashing my bike at 100mph and taking a lot of skin off my body.

"What scares me is lying there when I am old and not able to ride a bike and thinking I did not give it 100 per cent or I didn’t try this.’ I agree – that’s what it’s like for me.

“There are things I still want to accomplish and when I finally decide to hang up my clubs I want to know I’ve given it everything. If I don’t do that I will not be able to sleep and that would just be no good for me.”

While he missed the cut at the Dunhill Links, Casey had a round he will never forget on Friday when a dog ran off with his ball on the 12th green

He said: “Fortunately we got the ball back, without any teeth marks, and put it back where we thought it originally was and I still got a birdie.”
